The Killer B 1/2″ NPT to 1/8″ NPT or PT Adapter will allow the use of aftermarket temperature sensors that have 1/8 NPT or PT threads. The Killer B aftermarket oil pan includes an extra 1/2NPT port that can be used with this adapter. Measure the oil temperature where it should be, in the pan!

Select your gauge sender thread style — NPT or PT (also known as BPT/BSPT).

The NPT-to-PT style adapter is custom-CNC machined, so it costs a little more.
